摘要
位于永登拗陷北缘的天祝炭山岭盆地出露的中侏罗统窑街组地层,是一套湖沼相煤系地层.有机地化研究表明,窑街组的油页岩是可能的生油岩,且已进入成熟阶段.这对评价民和盆地北部拗陷(即永登拗陷)的含油气前景提供了实际资料.
The Tanshanling basin of Tianzhu is located at the north edge ofYongdeng seg,in which appear the middle Jurassic series named Yaojiegroup which is a set of limnetie facies coal measure stratum.The organicgeochemical studies show that the oil shale of Yaojie group is the possibleoil-producing rock which even has developed into the mature period.Allthese provide the practical materials for the appraisal of oil-gas prospectof the northern part seg of Minhe basin(namely seg).
